Objective To investigate the current basic situation of ultrasound machines of ultrasound departments in Shanghai medical institutions, and to provide the basis for making management policy in order to promote medical quality. Methods Questionnaire surveys about ultrasound machines and service ability including producing countries of ultrasound machines, the number of ultrasound machines, using years of ultrasound machines, yearly workload and the yearly number of patients that each ultrasound machine accepted were made in 2013 and 2018, respectively. Statistical results were compared between the two surveys. Results Compared with 2013, the share of imported ultrasound machines declined in 2018 (82% vs 91%). Compared with 2013, the number of ultrasound machines in Shanghai medical institutions had increased by 31% in 2018 (2 123 vs 1 617). The occupancy rate of ultrasound machines in tertiary hospitals was the highest (tertiary hospitals 40%, secondary hospitals 25%, primary grade hospitals 20%, and private hospitals 15%). Compared with 2013, the proportion of ultrasound machines that have been used for more than 10 years increased (9% vs 4%), the yearly workload of ultrasound examination had increased by 46% (19.82 million person-time vs 13.59 million person-time). Tertiary hospitals bored the highest proportion of the workload (tertiary hospitals 51%, secondary hospitals 35%, primary grade hospitals 4%, and private hospitals 10%). Currently, the number of ultrasound machines per 10, 000 people in Shanghai was 1.14. The yearly number of patients that each ultrasound machine accepted had increased by 11% (9300 person-time vs 8400 person-time in 2018). Conclusions The scale of ultrasound departments in Shanghai medical institutions has been developing. Brand localization of ultrasound machines is improving. However, the renewal ability of ultrasound machines still needs to be improved. The workload of ultrasound department is getting heavier. Hierarchical diagnosis and treatment is unbalanced.

Objective To explore the application value of pressure-strain loop (PSL) in evaluating left ventricular myocardial work (MW) in patients with chronic heart failure (CHF). Methods Seventy patients with CHF were selected as case group(CHF group) and were divided into 2 groups according to the left ventricular ejection fraction (LVEF) in ultrasonic cardiogram: LVEF preserve group (HFpEF group, LVEF≥50%, n=35) and LVEF reduced group (HFrEF group, LVEF<50%, n=35). Thirty-three healthy volunteers were selected as control group at the same period. Two-dimensional dynamic images in apical two chamber, three chamber and four chamber views were collected by two-dimensional speckle-tracking. Using the off-line EchoPAC software, a tracing analysis was conducted and the blood pressure was entered to obtain left ventricular global longitudinal strain (GLS), global MW index (GWI), global constructive work (GCW), global wasted work (GWW) and MW efficiency (GWE). The differences of GLS and MW parameters (GWI, GCW, GWW, GWE) were compared between each groups, and Pearson correlation was used to analyze the correlation between MW parameters and LVEF. Results Compared with the control group and HFpEF group, the left atrial dimension(LAD), left ventricular end-diastolic dimension(LVDd), left ventricular end-diastolic volume(LVEDV), left ventricular end-systolic volume(LVESV) in HFrEF group increased, while LVEF decreased significantly(P<0.05). Compared with the control group, LAD in HFpEF group increased, the vaules of GLS, GWI, GCW were obviously lower in HFpEF group and HFrEF group(all P<0.05), GWW was higher and GWE was lower in HFrEF group(all P<0.05). GLS, GWI, GCW, GWE decreased and GWW increased in HFrEF group than those in HFpEF group, and all the differences were statistically significant(all P<0.05). In CHF group, GWW was negatively correlated with LVEF (r=-0.521, P<0.001) while positive correlations between GWI, GCW, GWE and LVEF were discovered (r=0.846, 0.807, 0.788; all P<0.001). Conclusions PSL can effectively evaluate the left ventricular MW in CHF patients. It has a certain correlation with LVEF and can reflect left ventricular systolic function. It provides a new reference index for the clinical diagnosis and evaluation of prognosis in CHF patients.

Objective To investigate the influences of cardiovascular risk factors on left ventricular wall motion function in patients treated with epirubicin chemotherapy by layer-specific two-dimensional speckle tracking imaging (2D-STI). Methods Sixty-four female patients with breast cancer treated with epirubicin and 36 controls from June 2018 to March 2019 in Renmin Hospital of Wuhan University were included. According to the numbers of cardiovascular risk factors, the patients were divided into group A (without cardiovascular risk factors, 31 cases), group B (single cardiovascular risk factor, 20 cases), and group C (multiple cardiovascular risk factors, 13 cases). All patients underwent echocardiography before and after epirubicin respectively. Global longitudinal strain, circumferential strain, radial strain (GLS, GCS, GRS), endocardial and epicardial layers of GLS and GCS (endoGLS, epiGLS, endoGCS, epiGCS) were obtained by EchoPAC software analysis. The differences of GLS, EndoGLS, EpiGLS, GCS, EndoGCS, EpiGCS and GRS before and after chemotheraphy were calculated as ΔGLS, ΔEndoGLS, ΔEpiGLS, ΔGCS, ΔEndoGCS, ΔEpiGCS and ΔGRS. Results Compared with before chemotherapy, GLS, EndoGLS, EpiGLS, GCS, EndoGCS, EpiGCS and GRS were significantly reduced in group A, B and C after chemotherapy (all P<0.05). ΔEndoGLS and ΔEndoGCS showed an increasing trend in groups A, B and C, with statistical significance (all P<0.05). Correlation analysis showed that after chemotherapy with epirubicin, the numbers of cardiovascular risk factors were significantly correlated with strain parameters, and the correlation coefficient of EndoGLS was relatively higher (r=-0.582, P<0.001). Conclusions Layer-specific imaging can reliably detect the influences of cardiovascular risk factors on the left ventricular wall motion function in breast cancer patients treated with epirubicin. Parameters reflecting the endocardial longitudinal systolic function are sensitive indicators for the early detectin of myocardial damage and toxicity by epirubicin in patients with multiple cardiovascular risk factors.

Objective To investigate the value of transrectal ultrasonography(TRUS) in the preoperative diagnosis and tumor T-staging of anorectal malignant melanoma(ARMM). Methods The clinical and ultrasound data of 19 patients(22 lesions) with ARMM confirmed by pathology from February 2008 to Apirl 2019 in Fujian Medical University Affiliated Union Hospital were collected. TRUS was performed within one week before pathological examination. The sonographic features were summarized, ultrasonic typing was performed according to the lesion size and growth pattern, and the accuracies of preoperative ultrasound diagnosis and tumor staging were analyzed. Results Among the 22 lesions, 63.64%(14/22) were with a distance of ≤3 cm between the anal verge and the lower margin of tumor, 68.18%(15/22) with regular shape, 81.82%(18/22) with clear boundary, and 63.64%(14/22) with Adler blood flow grading from Ⅱ to Ⅲ. The preoperative TRUS diagnostic coincidence rate was 73.68%(14/19), and the tumor T-staging accuracy was 75%(12/16), respectively. Conclusions TRUS exhibits certain sonographic characteristics, with high preoperative diagnosis rate and tumor T-staging accuracy in anorectal malignant melanoma, which is of great guiding significance for clinical diagnosis and treatment.

Objective To evaluate the left ventricular global systolic function and myocardial fibrosis in adult hypertrophic cardiomyopathy (HCM) patients by three-dimensional speckle tracking echocardiography(3D-STE) combined with cardiac magnetic resonance imaging-late gadolinium enchancemet (CMRI-LGE) sequence, and to explore the association between left ventricular global systolic function and myocardial fibrosis. Methods Thirty patients with HCM(HCM group) and 33 healthy controls(control group) were enrolled in the study. All patients underwent conventional two-dimensional echocardiography (2DE), tissue Doppler imaging (TDI), and 3D-STE. The following parameters were acquired and compared between the groups: interventricular septal end-diastolic thickness (IVSD), left ventricular posterior wall end-diastolic thickness (LVPWD), left ventricular mass(LVM), left ventricular mass index (LVMI), left atrial volume (LAV), and left ventricular end-systolic volume(LVESV), left ventricular end-diastolic volume (LVEDV), left ventricular outflow tract pressure gradient (LVOT-PG), left ventricular outflow tract velocity time integral (LVOT-VTI), isovolumic relaxation time (IVRT), global strain (GS), global longitudinal strain (GLS), global radial strain (GRS), global circumferential strain (GCS). And 28 patients who met the CMRI indications underwent CMRI-LGE to obtain the LVM, and the correlation and consistency of LVM results obtained from CMRI and 3D-STE were performed.According to LGE results, HCM patients were divided into LGE(+ ) group and LGE (-) group, the differences of GLS, GRS and GCS between the two groups were analyzed. Results ①Compared with the control group, IVSD, LVPWD, LVMI, LAV, LVOT-PG, LVOT-VTI and IVRT were significantly increased in the HCM group (all P 0.05), while GLS and GRS decreased and GCS increased significantly in HCM group (P<0.05); ③The correlation between 3D-STE and CMRI in measuring measured LVM in HCM patients was good, and the results showed good concordance(r=0.807, P<0.01). ④GLS in LGE(+ ) group was lower than in LGE(-) group(P=0.004), but there was no significant difference in GCS and GRS between the two groups(P=0.597, 0.534). Conclusions ①3D-STE can detect the early damage of left ventricular global systolic function in patients with HCM; ②3D-STE combined with CMRI-LGE technology can provide an important imaging reference for the evaluation of the relationship between left ventricular global systolic function and myocardial fibrosis in patients with HCM.

All patients underwent conventional two-dimensional echocardiography (2DE), tissue Doppler imaging (TDI), and 3D-STE. The following parameters were acquired and compared between the groups: interventricular septal end-diastolic thickness (IVSD), left ventricular posterior wall end-diastolic thickness (LVPWD), left ventricular mass(LVM), left ventricular mass index (LVMI), left atrial volume (LAV), and left ventricular end-systolic volume(LVESV), left ventricular end-diastolic volume (LVEDV), left ventricular outflow tract pressure gradient (LVOT-PG), left ventricular outflow tract velocity time integral (LVOT-VTI), isovolumic relaxation time (IVRT), global strain (GS), global longitudinal strain (GLS), global radial strain (GRS), global circumferential strain (GCS). And 28 patients who met the CMRI indications underwent CMRI-LGE to obtain the LVM, and the correlation and consistency of LVM results obtained from CMRI and 3D-STE were performed.According to LGE results, HCM patients were divided into LGE(+ ) group and LGE (-) group, the differences of GLS, GRS and GCS between the two groups were analyzed. \u0000 \u0000 \u0000Results \u0000①Compared with the control group, IVSD, LVPWD, LVMI, LAV, LVOT-PG, LVOT-VTI and IVRT were significantly increased in the HCM group (all P 0.05), while GLS and GRS decreased and GCS increased significantly in HCM group (P<0.05); ③The correlation between 3D-STE and CMRI in measuring measured LVM in HCM patients was good, and the results showed good concordance(r=0.807, P<0.01). ④GLS in LGE(+ ) group was lower than in LGE(-) group(P=0.004), but there was no significant difference in GCS and GRS between the two groups(P=0.597, 0.534). \u0000 \u0000 \u0000Conclusions \u0000①3D-STE can detect the early damage of left ventricular global systolic function in patients with HCM; ②3D-STE combined with CMRI-LGE technology can provide an important imaging reference for the evaluation of the relationship between left ventricular global systolic function and myocardial fibrosis in patients with HCM. \u0000 \u0000 \u0000Key words: \u0000Echocardiography; Three-dimensional speckle tracking imaging; Cardiomyopathy, hypertrophic; Cardiac magnetic resonance imaging; Ventricular function, left; Myocardial fibrosis","PeriodicalId":10224,"journal":{"name":"Chinese Journal of Ultrasonography","volume":"29 1","pages":"6-12"},"PeriodicalIF":0.0,"publicationDate":"2020-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49393371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective To explore the feasibility of Sonography based Volume Computer Aided Display Heart (SonoVCADheart) in the display of the fetal ventricular outflow views, and compare diameters of fetal aorta (AO) and pulmonary artery (PA) measured by two-dimensional echocardiography (2DE) and SonoVCADheart. Methods Eighty singleton fetuses in the second and third trimesters of pregnancy in January 2019 in Sir Run Run Shaw Hospital, Zhejiang University College of Medicine were enrolled. Conventional 2DE examinations were performed. The volume datasets were analyzed offline using the new automatic image processing software SonoVCADheart. The diameters of AO and PA were measured by 2DE and SonoVCADheart, respectively. Pearson correlation analysis was used to evaluate the correlation between the two methods. The consistency of the two methods was verified by Bland-Altman analysis, and he reliability of SonoVCADheart was assessed using the intraclass correlation coefficient (ICC). Results Fetal ventricular outflow views were successfully obtained using SonoVCADheart in 73(91.2%) of 80 fetuses. There were good correlations between the two methods for measuring the diameters of AO and PA (r=0.953, 0.971; all P<0.001). The 95% agreement limits of AO and PA were (-0.669, 0.568)mm and (-0.632, 0.580)mm, respectively. ICC demonstrated that SonoVCADheart achieved great repeatability both between and within observers. Conclusions SonoVCADheart may have potentials for the quantitative evaluation of fetal ventricular outflow tracts with its good repeatability and reliability.

Objective To investigate the effects of modified acidic fibroblast growth factor (MaFGF) mediated by nanoliposomes combined with ultrasound-targeted microbubble destruction (UTMD) on left ventricular systolic function in early diabetes mellitus(DM) rats. Methods The nanoliposomes containing MaFGF(MaFGF-nlip) were prepared by reverse phase evaporation method. Among 60 male Sprague Dawley (SD) rats, 50 rats were randomly selected and were induced to be DM models by streptozotocin(STZ) through intraperitoneal injecting, the other 10 rats as control group. Then DM rats were randomly divided into 4 groups: DM model group, MaFGF solution group, MaFGF-nlip group and MaFGF-nlip+ UTMD group. After the successful induction of DM model, the intervention was performed twice a week.After 12 weeks of intervention, all rats underwent conventional echocardiography and velocity vector imaging (VVI). Left ventricular ejection fraction (LVEF) and left ventricular fraction shortening(LVFS) were measured by conventional echocardiography. The mean peak systolic radial velocity (Vs), radial strain (Sr) and radial strain rate (SRr) of six walls at the papillary muscle level were measured in left ventricular short-axis view by VVI. At last, myocardial tissue of all rats were stained with Sirius red to evaluate myocardial interstitial fibrosis. The level of myocardial apoptosis was evaluated by TUNEL staining, and the changes of myocardial ultrastructure were observed by transmission electron microscopy. Results The prepared MaFGF-nlip were more rounded, evenly dispersed, and of good stability and high encapsulation efficiency. Twelve weeks later after intervention, LVEF, LVFS, Vs, Sr and SRr in the DM model group were significantly lower than those in the control group (all P<0.05). LVEF, LVFS, Vs, Sr and SRr in the MaFGF-nlip+ UTMD group were significantly higher than those of the DM model group and other intervention groups (all P<0.05). The results of Sirius red staining and Tunel staining showed that CVF and AI in the DM model group were significantly higher than those in the control group (all P<0.05). For MaFGF-nlip+ UTMD group, CVF and AI were significantly decreased compared with the DM model group and other intervention groups(all P<0.05). According to the results of transmission electron microscopy, compared with the DM model group, the improvement of myocardial ultrastructure was the most obvious in the MaFGF-nlip+ UTMD group. Conclusions MaFGF delivered by using nanoliposomes combined with UTMD can improve the left ventricular systolic function in diabetic rats by inhibiting the myocardium cardiac fibrosis and reducing the cardiomyocyte apoptosis.

Objective To prepare a novel magnetic heating phasetransition nanoparticle contrast agent (PFH-HIONS), and to study its performance on enhancing photoacoustic imaging, magnetic resonance imaging and ultrasound imaging after phasetransition by magnetic-thermo in vitro. Methods Firstly, the superparamagnetic nano hollow iron spheres (HIONS) were prepared by a one-pot solvothermal method, and then the phasetransition liquid perfluorocarbon (PFH) was loaded on the HIONS by vacuum adsorption to obtain PFH-HIONS. After characterization of the nanoparticles, photoacoustic imaging, magnetic resonance imaging and ultrasound imaging after phasetransition with magnetic-thermo were performed in vitro, and the results were analyzed by a software. Results PFH-HIONS was successfully prepared with uniform particle size of (537.3±24.8)nm. PFH-HIONS could apparently enhance photoacoustic imaging and magnetic resonance imaging in vitro. In an alternating magnetic field, it could significantly increase the temperature, which promotes phasetransion of the PFH to produce microbubbles, thereby enhancing ultrasound imaging. Furthermore, as the concentration increased, the imaging intensity was enhanced, and the differences in imaging intensity between different concentration groups were statistically significant (P<0.05). Conclusions The PFH-HIONS can enhance the multimodal imaging including ultrasound, photoacoustic and magnetic resonance, and it also has obvious magnetic heating performance. It provides a new and efficient research platform for theranostics based on molecular imaging, therefore it has promising application prospects.

Objective To explore the application value of virtual touch tissue imaging quantification(VTIQ) technology in initial polymyositis(PM). Methods Sixteen PM patients collected from February 2016 to March 2019 in Wenzhou People′s Hospital were selected as PM group, and 33 healthy subjects as healthy control group. After gray and color Doppler ultrasound, the shear wave velocity(SWV) values of target muscle and control muscle in the same side of affected limb were measured by VTIQ technique. Maximum velocity(Vmax) and minimum velocity(Vmin) were measured, average velocity(Vmean) and standard deviation(SD) were calculated, and compared between the two groups. SWV difference and ratio between target muscle and control muscle were calculated, and creatine kinase(CK) was detected in the same day. Results Part of PM patients had abnormal ultrasonographic manifestations of full muscle shape (31.25%), increased or decreased echo of muscle bundles (56.25%), blurred muscle texture (25.00%) and increased blood flow signals (37.50%). There were significant differences in Vmin, SD, and Vmax difference, Vmin difference, Vmean difference, and Vmax ratio, Vmin ratio, and Vmean ratio between PM group and healthy control group (all P<0.01). The ROC curve analysis showed that the diagnostic efficiency of Vmin was lower than those of Vmin difference and Vmean difference, Vmin ratio and Vmean ratio with very close diagnostic efficiencies of the latter four parameters. The correlation analysis showed that Vmin difference and Vmean difference were moderately correlated with CK value(r=0.512, 0.601; all P<0.05). Conclusions Reduced VTIQ values or relative reduction of VTIQ values compared with other non-involved muscles are the manifestations of initial PM, VTIQ have certain diagnostic efficacy for initial PM.
